Reporters asked Harbaugh why Seattle's secondary wasn't repeatedly flagged in the Thursday night game, and he promised to "take that up with the" league office.
"I don't think a guy should be able to speak out and go ahead and cause an investigation," Carroll told ESPN Seattle on Monday. "That's too easy. I don't think that's going to happen. ...
"Wasn't it just a couple week ago, when (the 49ers) were talking about not doing things like that, with the Giants or Kevin Gilbride or something like that?" Carroll said. "I thought there was something about that, where we don't go out and express our concerns at all."
Niners quarterback Alex Smith argued after the game that Sherman and Browner should have drawn multiple illegal-contact penalties. Smith's receivers -- Kyle Williams, Michael Crabtree and Randy Moss -- didn't make much noise in the game.
"I think that this was a very normal game ... in terms of how we played," Carroll said. "I'm surprised that (Harbaugh) felt like the receivers were so overwhelmed. I thought our guys did a good job. There's always going to be some calls that you can look at, but our guys played good, solid, hard football. Vernon Davis didn't get the ball, and their receivers didn't do much, and Randy (Moss) got one, so I'm sure there's a little frustration there.
"If the officials look at it, they won't have anything to even look at, and I don't even think they need to. It's a regular game."
Harbaugh isn't happy with what he saw, but Carroll is. The league and its officials can break the tie, but we don't expect much to come of this one.
